In the movie, John Cusack's character would climb through a long tunnel and come out the other side feeling as if he were another person – inside of them, seeing and feeling the world through that person's eyes.

(In a twist, that person would always be the actor John Malkovich, who plays a fictionalized version of himself in the movie.)

Anyway, I bring this up because Twitter's new social media app for the iPhone, Vine, is the closest thing to a real-life Being John Malkovich I have ever seen.

For six seconds, you see and hear the world through someone else's eyes.
